Not a guarantee. A hygiene check of the source at the commit shown, not a security audit.

Rescanned at commit b426deb09e46, unchanged since the check below.

NETWORK_NO_FIXED_HOST NETWORK_UNNAMED_HOST SECRETS_PATH_DOTENV SECRETS_ENV_READ

Why this grade

  • NETWORK_NO_FIXED_HOST Low

    Makes a network call whose host is not written as a fixed address.

    skills/senderkit-integration/references/examples.md, line 33 curl -sS -X POST https://api.senderkit.com/v1/send \

  • NETWORK_UNNAMED_HOST Low

    Calls a fixed host that the description does not name.

    skills/senderkit-integration/references/examples.md, line 33 curl -sS -X POST https://api.senderkit.com/v1/send \

  • SECRETS_PATH_DOTENV Low

    Mentions a .env file.

    skills/senderkit-integration/references/verification.md, line 8 - `.env.example`, deployment docs, or secret manifests mention the new key without real values.

  • SECRETS_ENV_READ Note

    Reads an environment variable whose name contains KEY, SECRET, TOKEN, PASSWORD or CREDENTIAL.

    skills/senderkit-integration/references/examples.md, line 57 const senderkit = new SenderKit({ apiKey: process.env.SENDERKIT_API_KEY! });

Any High, or two or more Medium findings, give D. One Medium gives C. Low findings or a security Note give B. Each code names a finding behind the letter.

Grades are a hygiene check of the source at the commit shown, on the date checked, not a security audit or a guarantee. The free directory grades are automated. Before release, a PlugVet engineer reviews every paid report and any grade we hold back, including all F grades, against the source code and the evidence we quote.
